There was a long thread on this:

Debate hinged on what type of book to produce: on-demand such as Blurb or through a fine-art photographic publisher. There were questions about who should judge a photo's worth and I think that APUG's make up of both professional photographers and keen amateurs compounded these discussions. Many in the former group see a book as an avenue for promotion and understandably want only to be involved if the publication is of the highest quality. Perhaps others would just like to take part in a fun collaborative effort and have a nice book on their shelves at the end of it.
